The portion 1) is cut away or recessed at d, and Theinvention has for its object to do away in the center of such recess apart or tongue is with the ordinary straight hinge-joint and to leftwhich is formed up into the tubular male provide in place thereof ahinge in which the portion 9 of the knuckle, said portion being knuckleand pintle or pin are curved, the adapted to extend lIlEO the recess 0,which is I5 curvature of the knuckle being on an arc and of shape andsize to receive said portion g.

In order to 50 sponding parts. allow thecentral portion g of the knuckle to a and I) represent the two portionsof the move for a half-rotation around the curved stationary pin, it isnecessary, therefore, that the opposite sides should be oppositelycurved in the manner above described, so as to give room for the pintleduring the swinging of the cover. This extra space, which is, of course,largest at the center of the portion g, is well illustrated in Fig. 4,and the opposite curvatures whereby such space is produced areillustrated in Figs. 3 and 5. Thus the locket is provided with ahinge-joint which is within or flush with its periphery, does notproject, and consequently will not catch, and operates freely, althoughthe pintle is both curved and stationary.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a locket consisting of a body portion and cover connected by ahinge-joint, the

portion a. formed with the curved tubular portions 6 of the knuckle ofthe hinge separated by a central space, said knuckle portions 6 beingsubstantially fiush with the periphery of the portion a but notprojecting outward therefrom; the portion Z) formed with the tubularportion g of the knuckle whose opposite walls g' and g are oppositelycurved, thereby forming a portion of an ellipse, the outer Wall beingcurved substantially in line With the curvature of the periphery of theportion 5, and the inner wall being curved inward to the same extent asthe outer wall is curved outward, said knuckle portion g beingsubstantially flush with but not extending outward from the portion 1);and a curved pintle or pin rigidly secured at its opposite ends in theportions 6 of the knuckle but free in the portion g, substantially asset forth.

2. In a locket consisting of a body portion and cover connected by ahinge-joint, the portion Ct formed with the curved tubular knuckleportions 6 of the hinge, the outer Walls of said knuckle portions beingon an arc of the same circle with and continuous with the periphery ofthe said portion a, and the outer and inner walls of said knuckleportions being concentric; a curved pintle or pin secured within saidknuckle portions and concentric therewith; and the portion Z) formedwith the knuckle portion g adapted to extend between said portions 6,the outer wall 9 of said knuckle portion 9 being, when the locket isclosed, in line with the outer walls of the knuckle portions 6 and beingon an arc of the same circle as the knuckle portions e on the peripheryof the locket, and the inner wall g being formed on a corresponding butopposite arc, whereby space is provided for the rotation of the knuckleportion g around the fixed curved pintle, the entire hinge-joint forminga part of but not projecting from the curved periphery of the locket,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

WILLIAM H. BLANEY.
